Someone help me with the new math here. In 1983, a window sticker price:$12,487 in 1983. Sale price in 2015: $15,900. So, if a train is running west on a track at 60 mph and a train is running on the same track east headed right for the other train at 60 mph. (sorry for the mph my brothers from the north). Skip to the answer: how does the seller figure the $3500 addition over window sticker?... Remember to carry the one!
Part B: Is Katy Perry included in the sale with the $15,900?
